7.4) Electric system
Effectivity: 582 UL
Edition 3 / Rev. 0
The engine types 582 UL DCDI mod. 99 / mod. 17 are equipped
with a breakerless dual capacitor discharge ignition unit with in-
tegrated generator.
The ignition unit is completely free of maintenance and needs
no external power supply.
Two charging coils fitted on the generator stator and independ-
ent from each other feed one each ignition circuit. The energy
supplied is stored in the ignition capacitor. At the moment of
ignition the external triggers supply an impulse to the control cir-
cuits and the ignition capacitors are discharged via the primary
winding of the ignition coil. The secondary winding supplies the
high voltage for the ignition spark.
NOTE
The grey cable is provided for a rev-counter signal.
